Dataset Overview | National Centers for Environmental Information (NCEI)

Water temperature, salinity, and others taken by CTD from NOAA Ship Oscar Dyson, cruise DY1708, in the Bering Sea from 2017-09-23 to 2017-10-04 (NCEI Accession 0211794)

This dataset contains CTD (Conductivity-temperature-depth) profile data collected for a NOAA/EcoFOCI Fall mooring research cruise on board NOAA Ship Oscar Dyson (DY1708). The cruise spanned September 22 - October 7, 2017. CTD data collection spanned September 23 through October 4, 2017. Variables include dual temperature, dual salinity (calculated from conductivity), chlorophyll concentration, dissolved oxygen, oxygen saturation (%, calculated) and sigma-T (calculated). Station locations include a subset of the established 70-meter isobath line between PMEL/EcoFOCI mooring stations M2 (56.87 N,164.05 W) and M8 (62.20 N,174.67 W), the defined "Unimak Box" at Unimak Island in the Aleutian Islands, and casts at mooring stations including some NOAA, National Marine Mammal Lab moorings and within the defined Distributed Biological Observatory (DBO) area 1. See NOAA DBO site for further information on DBO sampling areas, and NOAA EcoFOCI site for information on established CTD lines.

Data are delivered as 13 columns of comma-separated values (csv) preceded by a 51-line metadata header, a blank line, then a 1-line header defining columns. Data quality assessment included omitting or interpolating obvious outliers and spikes, calibrating from water samples when appropriate, and at times extrapolating values to the surface in the top 5-10 meters due to surface conditions and to the difficulty in obtaining accurate near-surface data values. Missing data are represented as 1.0e+35.
